Vegetable oil processing equipment

Vegetable oil processing equipment is generally carried out in two ways, one is the physical way, the other is the chemical way. Physical refining USES steam stripping under vacuum to remove free fatty acids, unsaponifiable matter and odors. Chemical refining USES alkaline water and other methods to remove free fatty acids, unsaponifiable matter and other substances. Even if the use of edible alkali is harmless to human health, it will destroy some vitamins and minerals in oils and fats. The advantage is that the pretreatment of oil is not as high as that of physical refining. Decolorization process the use of bleached soil, bleached soil cooking oil if the deodorization process is not in place, the processed cooking oil will have a slight earthy smell.
